I searched but didn't find the answer to my question in previous posts, so i am going to throw it out to all the pros..
I have written a script for solaris zone creation, and part of this script has you select the lun that you wish to build the zone on. It is currently really messy in this part, and needs to be constantly modified as the number of luns grows.
What i am looking for is a way to have this be dynamic (ie if $DISK25 exists then have that be a valid selection in the menu). I know that a case statement is probably not the best way to do this, and maybe a select would work? The script works in its current incarnation, but i am looking for a way to avoid having to continuously add lines to the case statement as we add more and more luns, as well as get the number of lines in the code down..
Code:
#!/bin/ksh
#set -x
<jump to relevant code>
function zone_disk
{
header
echo | /usr/bin/pfexec format
print
print -n "Enter the number of the disk you wish to use for this zone (or q to exit): "; read DISKINFO
clear
header
case $DISKINFO in
0) DISKINFO=$DISK1; print; zpool_vdev; print "You have selected $DISKINFO";;
1) DISKINFO=$DISK2; print; zpool_vdev; print "You have selected $DISKINFO";;
2) DISKINFO=$DISK3; print; zpool_vdev; print "You have selected $DISKINFO";;
3) DISKINFO=$DISK4; print; zpool_vdev; print "You have selected $DISKINFO";;
4) DISKINFO=$DISK5; print; zpool_vdev; print "You have selected $DISKINFO";;
5) DISKINFO=$DISK6; print; zpool_vdev; print "You have selected $DISKINFO";;
6) DISKINFO=$DISK7; print; zpool_vdev; print "You have selected $DISKINFO";;
7) DISKINFO=$DISK8; print; zpool_vdev; print "You have selected $DISKINFO";;
8) DISKINFO=$DISK9; print; zpool_vdev; print "You have selected $DISKINFO";;
9) DISKINFO=$DISK10; print; zpool_vdev; print "You have selected $DISKINFO";;
10) DISKINFO=$DISK11; print; zpool_vdev; print "You have selected $DISKINFO";;
11) DISKINFO=$DISK12; print; zpool_vdev; print "You have selected $DISKINFO";;
12) DISKINFO=$DISK13; print; zpool_vdev; print "You have selected $DISKINFO";;
13) DISKINFO=$DISK14; print; zpool_vdev; print "You have selected $DISKINFO";;
14) DISKINFO=$DISK15; print; zpool_vdev; print "You have selected $DISKINFO";;
15) DISKINFO=$DISK16; print; zpool_vdev; print "You have selected $DISKINFO";;
16) DISKINFO=$DISK17; print; zpool_vdev; print "You have selected $DISKINFO";;
17) DISKINFO=$DISK18; print; zpool_vdev; print "You have selected $DISKINFO";;
18) DISKINFO=$DISK19; print; zpool_vdev; print "You have selected $DISKINFO";;
19) DISKINFO=$DISK20; print; zpool_vdev; print "You have selected $DISKINFO";;
20) DISKINFO=$DISK21; print; zpool_vdev; print "You have selected $DISKINFO";;
21) DISKINFO=$DISK22; print; zpool_vdev; print "You have selected $DISKINFO";;
22) DISKINFO=$DISK23; print; zpool_vdev; print "You have selected $DISKINFO";;
<code snipped, as each additional line is more of the same in this case>
esac
and this is the part of the code where i get the $DISK# varaible for the case statement above
Code:
# this function gets the cxtxdx numbers of the disks and assigns them to variables
function disk_numbers
{
# echo cxtxdx numbers to a variable
CTDNUM=`echo | /usr/bin/pfexec format | grep c.t | awk '{print $2}'`
echo $CTDNUM > /tmp/disk
# count the disks for the counter and passing number to an integer
typeset -i DISKS=$(nawk -F' ' '{print NF;exit}' /tmp/disk)
integer cnt=1
#typeset -i
while (( cnt <= DISKS ))
do
eval DISK$cnt=`echo $CTDNUM | awk '{print $'$cnt'}'`
cnt=$cnt+1
done
/usr/bin/pfexec rm /tmp/disk
}
hopefully my question makes sense, but if there are any questions I will promptly answer them
I am by no means a pro at coding, so any help would be greatly appreciated!
print -n "Enter the number of the disk you wish to use for this zone (or q to exit): "; read DISKINFO

DISKINFO=\$DISK$DISKINFO;

hello,
i thought this should work to specify that i want to "cp" all files no matter what the case, ie upper or lower, as i have 2 files called Makefile and mak
cp -i mak*
but apparently the -i isn't a valid option like it is with grep
thanks for any suggestions!
